Homogeneous　Ba-Ti-B-Si,　Ba-Ti-Al-Si　and　Ba-Ti-B　gels　have　been　successfully　prepared　by　the　sol-gel　process.　A　novel　method　is　presented　for　fabricating　barium　titanate　glass-ceramics　by　sintering　the　gel　powders　with　small　barium　titanate　crystallites.　The　structural　development,　grain　size,　crystallization　process　and　dielectric　properties　were　systematically　studied　by　differential　thermal　analysis,　thermogravimetric　analysis,　X-ray　diffraction　techniques,　scanning　electron　microscopy　and　dielectric　measurements.　The　glass-ceramic　samples　were　sintered　at　lower　temperatures　compared　to　the　barium　titanate　ceramic　sintering,　and　showed　improved　dielectric　properties.　It　was　found　that　the　small　size　effect　of　the　barium　titanate　grains　on　the　dielectric　constant　in　the　glass-ceramics　was　quite　evident.　Ferroelectric　hysteresis　loop　analyses　were　also　performed　to　manifest　the　ferroelectric　nature　of　the　barium　titanate　grains　in　situ　grown　from　the　gels.
